Definitions
- the invention relates to the field of plate processing and connection, and in particular to a table assembly structure and table processing and splicing technology.
- Tables are one of the indispensable pieces of furniture in current home life. Tables are divided into dining tables, office desks, coffee tables, desks, etc., and the whole structure is fixed. With the current trend of e-commerce, online sales Products need to be shipped to customers by logistics, so for tables that need to be transported over long distances, the table as a whole takes up a lot of transportation space, and the packaging volume is large, making it difficult to place the table during transportation and making transportation very inconvenient; therefore, the transportation cost of the product will be will increase; tables that facilitate packaging and transportation and reduce packaging and transportation costs will bring higher benefits to companies and manufacturers. For a table, the part that takes up the most packaging volume is the table board.
- a single table board is thick and heavy, making it difficult to package and transport, and it is not conducive to allocating the occupied space during transportation. Therefore, many tables on the market now divide the table board into multiple pieces. Small table boards are spliced together to form a tabletop, thereby solving the above problems; in addition, the splicing structure between the small table boards after dividing the table boards can adopt a variety of methods.
- the table splicing structures currently on the market mainly include the following types:
- one of the two adjacent table boards is provided with a latch or a mortise, and the other of the two table boards is correspondingly provided with a jack or mortise; when the two tables are connected, The boards can be plugged together.
- This structure has the advantages of easy positioning, quick connection, and the ability to eliminate connection traces after connection.

- the table boards When in use, the table boards are spliced together through tongues and slots. After use, the table boards are disassembled and the table legs are folded, occupying less storage space. This allows the room to be fully utilized.
- this type of structure also has an obvious shortcoming: the connection strength is not enough.
- the two boards are only supported by the plug-in part. If one of the boards is pressed hard, the board will sink relative to the other board due to the force. There is a height difference between the other boards, which means that uniform force cannot be ensured and connection stability cannot be guaranteed; and the two table boards cannot be locked.

Description
本发明涉及板材加工连接领域,特别涉及一种桌板装配结构和桌板加工及拼接工艺。The invention relates to the field of plate processing and connection, and in particular to a table assembly structure and table processing and splicing technology.
桌具是当前居家生活中必不可缺的家具之一,桌具分为餐桌、办公桌、茶几以及书桌等等,且整体均为固定结构;而随着当下电商化的趋势,线上销售的产品需由物流发给顾客,于是对于需要长途运输的桌子来说,桌子整体非常占用运输空间,包装体积较大,使得桌子在运输时不易安放且运输很不方便;于是产品的运输成本将会增加;继而方便包装运输并减少包装运输成本的桌具将会为公司与厂家带来更高的效益。对于桌具来说最占用包装体积的部分即为桌板,单块桌板厚重,不易包装运输,也不利于分配运输时的占用空间,故而现在市面上的很多桌子将桌板分割成多块小桌板,由这些小桌板拼接形成桌面,从而解决上述问题;此外,分割桌板后小桌板之间的拼接结构可以采用多种方式。Tables are one of the indispensable pieces of furniture in current home life. Tables are divided into dining tables, office desks, coffee tables, desks, etc., and the whole structure is fixed. With the current trend of e-commerce, online sales Products need to be shipped to customers by logistics, so for tables that need to be transported over long distances, the table as a whole takes up a lot of transportation space, and the packaging volume is large, making it difficult to place the table during transportation and making transportation very inconvenient; therefore, the transportation cost of the product will be will increase; tables that facilitate packaging and transportation and reduce packaging and transportation costs will bring higher benefits to companies and manufacturers. For a table, the part that takes up the most packaging volume is the table board. A single table board is thick and heavy, making it difficult to package and transport, and it is not conducive to allocating the occupied space during transportation. Therefore, many tables on the market now divide the table board into multiple pieces. Small table boards are spliced together to form a tabletop, thereby solving the above problems; in addition, the splicing structure between the small table boards after dividing the table boards can adopt a variety of methods.
现有市面上的桌板拼接结构主要有以下几种:The table splicing structures currently on the market mainly include the following types:
一、采用插接式的结构,在相邻两个桌板的其中一个上设有插销或者插榫,在两个桌板的另一个上相应设有插孔或者榫眼;连接时两个桌板插接对合即可,该结构具有找位方便、连接迅速,且连接后能够消除连接痕迹的优点。如专利号CN201610213091.6公开的一种拼接方桌,其包括四块相拼接的桌板,该些桌板分别具有相互垂直的两条外边,以及与另外两块桌板相吻合接触的两条内边,该些内边上设有插槽或插舌,该些桌板各自的底面分别设有桌脚。该发明结构简单、组装方便,在使用时通过各桌板之间的插舌和插槽拼接起来,用完再将各桌板拆开,将桌脚折叠,占用较少的收纳容间,这样便令室内容间得到充分利用。但是该类结构也具有一个明显的缺点:那就是连接强度不够,两个板之间仅通过插接部分进行支撑,如果用力按压其中一块板,则该板受力会相对另一块板下陷,与另一块板之间产生高低落差,也就是无法保证均匀受力,也无法保证连接稳定性;并且也无法将两个桌板进行锁紧。1. Adopting a plug-in structure, one of the two adjacent table boards is provided with a latch or a mortise, and the other of the two table boards is correspondingly provided with a jack or mortise; when the two tables are connected, The boards can be plugged together. This structure has the advantages of easy positioning, quick connection, and the ability to eliminate connection traces after connection. For example, patent number CN201610213091.6 discloses a spliced square table, which includes four spliced table boards. The table boards respectively have two mutually perpendicular outer edges, and two inner edges that are in consistent contact with the other two table boards. The inner edges are provided with slots or tongues, and the bottom surfaces of the table boards are respectively provided with table legs. The invention has a simple structure and is easy to assemble. When in use, the table boards are spliced together through tongues and slots. After use, the table boards are disassembled and the table legs are folded, occupying less storage space. This allows the room to be fully utilized. However, this type of structure also has an obvious shortcoming: the connection strength is not enough. The two boards are only supported by the plug-in part. If one of the boards is pressed hard, the board will sink relative to the other board due to the force. There is a height difference between the other boards, which means that uniform force cannot be ensured and connection stability cannot be guaranteed; and the two table boards cannot be locked.
并且采用插销连接的话,需要在每个桌板的拼接侧壁上加工成排的孔位;现有的常规做法是使用普通钻床在桌板上依次加工单个孔,使这些孔位形成排孔;这样无疑加工效率低,且很难保证这些孔的孔位处于同一水平线。对于用于拼接的桌板而言,如果用于连接插销的孔位不是同一水平线,会导致拼接后两个桌板之间不平整,且受力时容易集中在几个插销上,导致受力不分散,结构不稳定。所以由于孔位数量以及位置的要求,使得通过人工以及普通钻床进行加工操作很是麻烦,而且效率不高,孔的形位公差也不好控制,很容易浪费材料。And if pin connection is used, rows of holes need to be processed on the spliced side walls of each table board; the existing conventional method is to use an ordinary drill machine to process individual holes on the table board in sequence, so that these holes form rows of holes; This undoubtedly has low processing efficiency, and it is difficult to ensure that the hole positions of these holes are at the same level. For table boards used for splicing, if the holes used to connect the pins are not on the same horizontal line, it will cause unevenness between the two table boards after splicing, and the stress will easily be concentrated on a few pins, resulting in stress Not dispersed and structurally unstable. Therefore, due to the requirements on the number and location of holes, it is very troublesome to perform manual processing operations and ordinary drilling machines, and the efficiency is not high. The shape and position tolerance of the holes is not easy to control, and it is easy to waste materials.
二、采用常见的三合一连接件对两个桌板之间进行组装。如专利号CN202021818402.X 公开的一种三合一连接件;包括:连接杆,一端设置有外螺纹,并与其中一块木板螺纹连接,连接杆的另一端设置有锁紧槽;螺母,预埋于另一块木板内,其中,螺母上开设有一个与连接杆环形套管配合的通槽,和一个与通槽垂直设置的螺纹孔;锁紧螺帽,与螺纹孔螺接配合,并与锁紧槽抵靠卡接配合。本实用新型提供的一种三合一连接件,通过连接杆与螺母之间的环形套管配合,锁紧螺帽与螺母之间的螺纹配合以及锁紧螺帽与连接杆之间的抵靠卡接,从而提高三者之间的防松效果,减小相邻两块木板之间的拼缝距离,进而提高相邻两块木板之间连接的牢固性和承载力。采用三合一连接件将两个木板拼接在一起的方式是当前现有技术中较为常见的一种应用结构。但是三合一连接件主要是针对两个相互垂直的板件之间进行连接,用于橱柜等家具结构中;因为两个相互垂直的板之间的力的挤压方向与三合一连接件的连接杆长度方向一致,故而能够保证结构稳定。而如果用于水平的两个拼接桌板的话,单靠三合一连接件进行受力的话;如果用力按压其中一块板,该板受力会相对另一块板下陷;从而会垂直撬动连接杆;长时间使用的话,使得连接杆具有螺纹的一端容易松动,导致连接杆脱离;存在连接不稳固的隐患。2. Use common three-in-one connectors to assemble the two table boards. For example, the patent number CN202021818402. In another wooden board, the nut is provided with a through slot that matches the annular sleeve of the connecting rod, and a threaded hole set vertically with the through slot; the locking nut is threadedly matched with the threaded hole and with the lock. The tight groove fits against the snap fit. The utility model provides a three-in-one connector, which uses an annular sleeve fit between the connecting rod and the nut, a thread fit between the locking nut and the nut, and abutment between the locking nut and the connecting rod. The snap connection improves the anti-loosening effect between the three, reduces the joint distance between two adjacent wooden boards, and thereby improves the firmness and load-bearing capacity of the connection between the two adjacent wooden boards. The method of splicing two wooden boards together using a three-in-one connector is a relatively common application structure in the current prior art. However, the three-in-one connector is mainly used for connecting two mutually perpendicular plates and is used in cabinets and other furniture structures; because the extrusion direction of the force between the two mutually perpendicular plates is different from the three-in-one connector. The connecting rods have the same length direction, thus ensuring structural stability. And if it is used for two horizontal spliced table boards, if the three-in-one connector is used to bear the force alone; if one of the boards is pressed hard, the board will sink relative to the other board; thus the connecting rod will be moved vertically. ; If used for a long time, the threaded end of the connecting rod will easily loosen, causing the connecting rod to detach; there is a hidden danger of unstable connection.
针对上述问题,亟需设计一种对桌板的加工及拼接工艺,使得对桌板孔位加工方便,且孔位精度高;并能够保证两个桌板拼接后的结构强度以及平整度。In view of the above problems, there is an urgent need to design a processing and splicing process for table boards that makes it easy to process the hole positions of the table boards and has high hole position accuracy; and can ensure the structural strength and flatness of the two table boards after they are joined together.
本发明克服了现有技术中所存在的不足,提供了一种桌板加工及拼接工艺,通过采用排孔装置对桌板单元加工定位孔,再利用定位销以及三合一连接对桌板进行拼接;使得钻孔加工方便,且拼接后两个桌板单元之间结构稳固,且平整度高。The present invention overcomes the deficiencies in the prior art and provides a table processing and splicing process. The invention uses a hole arrangement device to process positioning holes for the table unit, and then uses positioning pins and three-in-one connections to perform positioning on the table. Splicing makes drilling easy, and after splicing, the structure between the two table units is stable and the flatness is high.
再进一步,本发明又提供了一种桌板装配结构,通过在桌板单元的嵌槽内加装环形套管,使得偏心轮紧固件与环形套管接触配合;继而偏心轮紧固件旋拧时,不会与桌板单元的内芯接触;从而使得受力均匀,偏心轮紧固件不会歪斜,使外观平整美观。Furthermore, the present invention provides a table assembly structure. By installing an annular sleeve in the slot of the table unit, the eccentric fastener is in contact with the annular sleeve; and then the eccentric fastener is rotated. When tightening, it will not come into contact with the inner core of the table unit; thus the force will be even, the eccentric fastener will not be skewed, and the appearance will be smooth and beautiful.

首先,本发明的桌板加工及拼接工艺,为了保证两个桌板单元拼接平整,故而对桌板单元上的定位孔加工要求高;采用排孔装置对桌板单元进行钻孔,使得操作时,用户只需将桌板单元放置在承托工位上;然后在侧部定位组件、前部定位组件以及定位压盘和定位压梁的作用下,能够将板材稳定的定位在承托台上;使得钻孔机构能够驱动成排的钻头同步进给以对桌板单元进行钻孔;一次工作即可使得桌板单元的拼接侧壁上的定位孔及过孔加工成型,且由于定位压梁能够稳固压住桌板单元后端,使得钻孔精度高,能够保证每个定位孔和过孔的中心保持在同一水平线上;使得在之后的拼接步骤中,两个桌板单元之间的定位销和连接杆处于同一高度,插接配合时,能够使得两个桌板单元平整拼接在一起,不会存在拼接处凹凸不平。且采用排孔装置能够实现对桌板单元的全自动化打孔,提高生产效率。First of all, in the table processing and splicing process of the present invention, in order to ensure that the two table units are spliced smoothly, the processing requirements for the positioning holes on the table units are high; a hole row device is used to drill the table units, so that during operation , the user only needs to place the table unit on the supporting station; then under the action of the side positioning component, the front positioning component, the positioning pressure plate and the positioning pressure beam, the plate can be stably positioned on the supporting platform ; The drilling mechanism can drive rows of drill bits to feed simultaneously to drill the table unit; the positioning holes and through holes on the spliced side walls of the table unit can be processed and formed in one operation, and due to the positioning pressure beam It can firmly press the rear end of the table unit, resulting in high drilling accuracy, and ensuring that the center of each positioning hole and via hole is kept on the same horizontal line; making the positioning between the two table units better in the subsequent splicing steps. The pin and the connecting rod are at the same height. When plugged together, the two table units can be spliced together smoothly without unevenness at the splicing joint. And the use of a hole arrangement device can realize fully automated drilling of table units and improve production efficiency.
其次,通过在嵌槽内预埋硬质的环形套管,使得偏心轮结构的紧固件在嵌槽内旋拧时不会与桌板单元挤压接触,而是直接与硬质的环形套管接触;这样设计的目的在于:普遍的桌板结构大致组成为:中间芯材以及芯材正反两面的硬质夹板,硬质夹板再外面是纸或贴面层;而对于一些中间芯材较软的桌板来说,比如中间的芯材是南洋楹,配备三合一连接件的话,如果紧固件直接与中间的芯材接触;继而当旋拧将连接杆拉紧时,紧固件将会会与芯材挤压接触,而由于芯材质地较软,导致紧固件可能会上下歪斜的嵌入芯材中,从而导致锁紧效果变差,也影响外观。而通过在嵌槽内预埋硬质的环形套管,紧固件直接与环形套管接触,使得受力均匀分散,从而使得紧固件能够保持正向的旋拧,不会偏转;保证锁紧效果,且美化外观。相应的,能够在紧固件的上端面上加工形成内六角沉槽。传统的紧固件采用十字沉槽,而由于本发明增设了环形套管,增加了连接处结构强度;紧固件能够承受更大的旋拧力,故而在紧固件上设置内六角沉槽,能够采用L型的内六角扳手进行旋拧紧固件,使操作更为省力轻松。Secondly, by embedding a hard annular sleeve in the slot, the fasteners of the eccentric structure will not come into extrusive contact with the table unit when screwed in the slot, but will directly contact the hard annular sleeve. pipe contact; the purpose of this design is that the common table board structure is roughly composed of: a middle core material and hard plywood on both sides of the core material, and the hard plywood is covered with paper or veneer layer; and for some middle core materials For a softer table top, for example, the core material in the middle is Nanyang Jacaranda, if equipped with a three-in-one connector, if the fastener is in direct contact with the core material in the middle; then when the connecting rod is tightened by twisting, the fastener will The parts will be in extrusion contact with the core material, and because the core material is soft, the fasteners may be embedded in the core material up and down, resulting in poor locking effect and affecting the appearance. By embedding a hard annular casing in the slot, the fasteners are in direct contact with the annular casing, so that the force is evenly distributed, so that the fasteners can maintain positive screwing without deflection; ensuring that the lock Tightening effect and beautifying appearance. Correspondingly, an internal hexagonal sink groove can be formed on the upper end surface of the fastener. Traditional fasteners use cross sink grooves, but because the present invention adds an annular sleeve, the structural strength of the connection is increased; the fasteners can withstand greater twisting force, so internal hexagonal sink grooves are provided on the fasteners. , the L-shaped hexagonal wrench can be used to tighten the fasteners, making the operation more labor-saving and easier.
再者,拼接后的两个桌板单元之间,由于定位销的直径大于连接杆的直径;使得定位销是粗于连接杆的,继而连接后定位销主要起到承载受力的作用;而连接杆主要起到将两块桌板单元拉紧的作用;两者各司其职,避免连接杆受力导致松动;使得两个桌板单元之间能够始终锁紧。Furthermore, between the two table units after splicing, since the diameter of the positioning pin is larger than the diameter of the connecting rod, the positioning pin is thicker than the connecting rod, and then the positioning pin mainly plays the role of bearing force after connection; and The connecting rod mainly plays the role of tightening the two table units; both perform their own duties to prevent the connecting rod from loosening due to force; so that the two table units can always be locked.

步骤二:如图3-12所示,采用排孔装置B依次对单个桌板单元a的拼接侧壁a1进行钻孔;从而方便在两个桌板单元a之间设置连接结构。所述的排孔装置B为本发明为了方便对桌板单元a进行孔位加工而设计的装置;排孔装置B包括工作台1,该工作台1上具有承托工位201,承托工位201处设有用于承载桌板单元a的承托台2,在承托台2的两侧设有侧部定位组件3;所述工作台1上还设有前后定位机构、上下定位机构;前后定位机构包括设置在工作台1后端的限位横板4及设置在工作台1前端的前部定位组件5;前部定位组件5包括用于将位于承托台2上的桌板单元a向后推至与限位横板4相抵的前定位推板6。上下定位机构包括设置在承托台2上方的能够升降调节的定位压盘7和定位压梁8,两者同时下压以将桌板单元a压紧在承托台2上。在限位横板4的后方设有对桌板单元a进行钻孔的钻孔机构9,钻孔机构9包括能够前后及上下移动调节的调节支座10以及沿左右方向设置在调节支座10上的一排钻头11。Step 2: As shown in Figure 3-12, use the hole row device B to drill holes in the spliced side wall a1 of a single table unit a in sequence; thus it is convenient to set up a connection structure between the two table units a. The hole arrangement device B is a device designed by the present invention to facilitate the hole processing of the table unit a; the hole arrangement device B includes a workbench 1, and the workbench 1 has a supporting station 201, which supports the workbench. Position 201 is provided with a supporting platform 2 for carrying the table unit a, and side positioning assemblies 3 are provided on both sides of the supporting platform 2; the workbench 1 is also provided with a front and rear positioning mechanism and an up and down positioning mechanism; The front and rear positioning mechanism includes a limiting horizontal plate 4 provided at the rear end of the workbench 1 and a front positioning component 5 disposed at the front end of the workbench 1; the front positioning component 5 includes a table unit a located on the supporting platform 2 Push back to the front positioning push plate 6 that abuts the limiting horizontal plate 4.

具体而言:如图4-10所示,所述工作台1位于承托台2的下方位置设有两条前后间隔的滑轨12,滑轨12沿左右方向延伸设置;在所述的承托台2底部的前后两侧分别设有滑动设置在每条滑轨12上的滑座13,从而使得承托台2整体能够沿滑轨12进行左右滑动;且在工作台1的其中一侧上设有用于驱动承托台2沿滑轨12滑动的滑动伸缩组件14,该滑动伸缩组件14包括连接在工作台1上的滑动驱动电缸14a,该滑动驱动电缸14a上的推杆连接在承托台2的底端;继而通过该滑动驱动电缸14a即可控制承托台2左右移动;使得桌板单元a定位在承托台2上后,通过控制承托台2左右移动能够进一步调节桌板单元a的左右位置。Specifically: as shown in Figure 4-10, the workbench 1 is located below the support platform 2 and is provided with two slide rails 12 spaced front and back. The slide rails 12 extend along the left and right directions; on the support platform 2 The front and rear sides of the bottom of the support platform 2 are respectively provided with sliding seats 13 slidably arranged on each slide rail 12, so that the entire support platform 2 can slide left and right along the slide rails 12; and on one side of the workbench 1 There is a sliding telescopic assembly 14 for driving the supporting table 2 to slide along the slide rail 12. The sliding telescopic assembly 14 includes a sliding driving electric cylinder 14a connected to the workbench 1. The push rod on the sliding driving electric cylinder 14a is connected to at the bottom of the supporting platform 2; and then the sliding drive electric cylinder 14a can control the supporting platform 2 to move left and right; after the table unit a is positioned on the supporting platform 2, the supporting platform 2 can be controlled to move left and right. Further adjust the left and right position of table unit a.
如图4、10所示,所述承托台2为板状结构,且承托台2包括两条前后间隔的并沿左右方向延伸设置的支撑横板2a,所述支撑横板2a配置为支撑桌板单元a;且每条支撑横板2a的上端面设有呈波浪状排布的凹槽15,凹槽15沿前后方向设置在支撑横板2a上。这样设计的目的是:如果支撑横板2a的上端面完全水平的话,桌板单元a与支撑横板2a的接触面积比较大,难以保证桌板单元a是完全挤压贴合在支撑横板2a上端面的,难免会存在间隙;而在支撑横板上端面设置凹槽15,能够减小支撑横板2a与桌板单元a之间的接触面积,使得两者接触处的上下挤压的压力更大,从而使得压紧定位效果更佳,定位更加牢固;结构设计巧妙,考虑更周到。所述的侧部定位组件3镜像设置在承托台3的左右两侧,侧部定位组件3包括定位侧板3a以及能够驱动该定位侧板3a左右移动的第一推拉驱动电缸3b;且在侧部定位组件3的前后两侧还分别设有条形的定位凸块16,且定位凸块16沿左右方向设置;当将桌板单元a置放在承托台2上时,先将桌板单元a的其中一侧端与两个定位凸块16的端部相抵,从而使得桌板单元a保持水平方正的放置在承托台2上;然后左右两侧的定位侧板3a能够分别在第一推拉驱动电缸3b的作用下朝桌板单元a靠近以将桌板单元a夹牢,使得在左右方向上,桌板单元a与承托台2相对固定。As shown in Figures 4 and 10, the supporting platform 2 has a plate-like structure, and the supporting platform 2 includes two supporting horizontal plates 2a spaced front and back and extending along the left and right directions. The supporting horizontal plates 2a are configured as Support the table unit a; and the upper end surface of each support horizontal plate 2a is provided with grooves 15 arranged in a wave shape, and the grooves 15 are arranged on the support horizontal plate 2a along the front and rear direction. The purpose of this design is: if the upper end surface of the supporting horizontal plate 2a is completely horizontal, the contact area between the table unit a and the supporting horizontal plate 2a is relatively large, and it is difficult to ensure that the table unit a is completely squeezed and fitted to the supporting horizontal plate 2a On the upper end surface, there will inevitably be a gap; and setting the groove 15 on the upper surface of the support cross plate can reduce the contact area between the support cross plate 2a and the table unit a, so that the up and down extrusion pressure at the contact point between the two Larger, which makes the compression and positioning effect better and the positioning more solid; the structure design is clever and more thoughtful. The side positioning assembly 3 is mirrored on the left and right sides of the supporting platform 3. The side positioning assembly 3 includes a positioning side plate 3a and a first push-pull driving electric cylinder 3b that can drive the positioning side plate 3a to move left and right; and There are also strip-shaped positioning bumps 16 on the front and rear sides of the side positioning assembly 3, and the positioning bumps 16 are arranged in the left and right directions; when placing the table unit a on the supporting platform 2, first One end of the table unit a is against the ends of the two positioning bumps 16, so that the table unit a remains horizontally and squarely placed on the supporting platform 2; then the positioning side plates 3a on the left and right sides can be positioned respectively. Under the action of the first push-pull driving cylinder 3b, it approaches the table unit a to clamp the table unit a firmly, so that the table unit a and the supporting platform 2 are relatively fixed in the left-right direction.
如图4-9所示,所述的前部定位组件5设置在工作台1上且位于承托台2前方,前部定位组件5包括所述的前定位推板6以及用于驱动该前定位推板6前后移动的第二推拉驱动电缸38a。所述的限位横板4处于直立状态并位于承托台2的后端,当所述的桌板单元a放置在承托台2上后,所述的前定位推板6将向后推动桌板单元a移动,使得桌板单元a的后端与限位横板4相抵,从而使得桌板单元a夹持在前定位推板6和限位横板4之间,使桌板单元a与承托台2沿前后方向相对固定。进一步的,如图4-5所示,沿左右方向,在所述的限位横板4上设有左右间隔排布的用于避让钻头11向前伸出的避让槽孔17;且在所述限位横板4前端的下部设有若干个向前伸出且呈左右间隔排布的支撑凸块4a,所述避让槽孔17位于两个支撑凸块4a之间;支撑凸块4a配置为支撑桌板单元a;且支撑凸块4a的上端面与承托台2的上端面齐平;具体的说:当所述桌板单元a的后端抵在限位横板4上时,桌板单元a底部将会抵接在支撑凸块4a上,此时支撑凸块4a和承托台2共同支撑桌板单元a;而相邻的两个支撑凸块4a之间相隔开;使得钻头11对桌板单元a进行钻孔时,桌板单元a的木屑刚好能够从两个支撑凸块4a的间隔处掉落下去;不然很容易在桌板单元a的下方积灰,导致桌板单元a被垫高或者影响机器工作;故而设置间隔的支撑凸块4a,在支撑桌板单元a的同时,能够使木屑掉落,避免积灰现象;结构设计巧妙。As shown in Figures 4-9, the front positioning assembly 5 is arranged on the workbench 1 and is located in front of the supporting platform 2. The front positioning assembly 5 includes the front positioning push plate 6 and is used to drive the front positioning push plate 6. The second push-pull driving electric cylinder 38a that moves the push plate 6 back and forth is positioned. The limiting horizontal plate 4 is in an upright state and is located at the rear end of the supporting platform 2. When the table unit a is placed on the supporting platform 2, the front positioning push plate 6 will be pushed backward. The table unit a moves so that the rear end of the table unit a is against the limiting horizontal plate 4, so that the table unit a is clamped between the front positioning push plate 6 and the limiting horizontal plate 4, so that the table unit a It is relatively fixed with the supporting platform 2 along the front and rear direction. Further, as shown in Figures 4-5, along the left and right directions, the limiting horizontal plate 4 is provided with escape slots 17 arranged at intervals on the left and right for avoiding the forward extension of the drill bit 11; The lower part of the front end of the limiting horizontal plate 4 is provided with a number of support bumps 4a that extend forward and are spaced left and right. The avoidance slot 17 is located between the two support bumps 4a; the support bumps 4a are arranged To support the table unit a; and the upper end surface of the support convex block 4a is flush with the upper end surface of the supporting platform 2; specifically: when the rear end of the table unit a is against the limiting horizontal plate 4, The bottom of the table unit a will be in contact with the support bump 4a. At this time, the support bump 4a and the supporting platform 2 jointly support the table unit a; and the two adjacent support bumps 4a are spaced apart; When the drill bit 11 drills the table unit a, the wood chips of the table unit a can just fall from the gap between the two support bumps 4a; otherwise, dust will easily accumulate under the table unit a, causing the table to be damaged. The board unit a is elevated or affects the operation of the machine; therefore, spaced support bumps 4a are provided to support the table board unit a while allowing sawdust to fall and avoid dust accumulation; the structural design is ingenious.
如图4-9所示,在所述工作台1后端的两侧设有向上伸出的立柱18,所述立柱18的上端设有向前伸出的U型的上悬架19,该上悬架19包括连接在立柱18上端并向前伸出的侧支撑梁191以及连接在两个侧支撑梁191之间的上支撑横梁192;所述的定位压盘7由纵向的第一升降电缸193控制升降;该第一升降电缸193的上端连接在上支撑横梁192上。定位压盘7配置为左右间隔设置的两个,且如图8所示,定位压盘7位于承托台2的正上方;继而定位压盘7能够初步下压使得桌板单元a压紧在承托台2上。As shown in Figure 4-9, there are upwardly extending columns 18 on both sides of the rear end of the workbench 1, and the upper end of the column 18 is provided with a forwardly extending U-shaped upper suspension 19. The suspension 19 includes a side support beam 191 connected to the upper end of the column 18 and extending forward, and an upper support beam 192 connected between the two side support beams 191; The cylinder 193 controls lifting; the upper end of the first lifting electric cylinder 193 is connected to the upper support beam 192. The positioning pressure plate 7 is configured as two spaced apart on the left and right, and as shown in Figure 8, the positioning pressure plate 7 is located directly above the supporting platform 2; then the positioning pressure plate 7 can be initially pressed down so that the table unit a is pressed against the On the supporting table 2.
进一步的:所述的定位压梁8也位于承托台2的上方,且定位压梁8设置在支撑凸块4a与承托台2交接位置的上方;这是由于钻孔时,是对桌板单元a的后端进行钻孔;仅通过定位压盘7压住桌板单元a,仍存在打孔时桌板单元a后端抖动现象;故而还设置定位压梁8,能够进一步压住桌板单元a靠后的位置,使得在打孔过程中,桌板单元a后端始终保持稳固;且该定位压梁8的后端距离限位横梁4的距离为1cm,使得定位压梁8能够稳定压住桌板单元a的后部打孔区域。且在所述工作台1后端的两侧分别设有用于驱动定位压梁8升降的第二升降电缸20,该第二升降电缸20的底部设有升降座21,第二升降电缸20能够控制该升降座21升降;且所述定位压梁8连接在该升降座21的前端;且如图11所示,在左右两侧的升降座21之间还设有同步机构22,同步机构22包括转动设置在每个升降座21内侧的转动连杆23,以及连接在两侧的转动连杆23之间的同步横轴24;在工作台1的后端的两侧还分别设有向上伸出的侧支撑台25,侧支撑台25上连接固定有向前伸出的固定支座26,所述同步横轴24转动穿设在两个固定支座26内;所述转动连杆23的前端与同步横轴24连接,转动连杆23的后端转动连接有一导轮231,在所述的升降座21的内侧壁相应沿前后方向设有与导轮231滑动配合的导槽232;继而,当所述两侧的第二升降电缸20同步驱动升降座21升降运动时,每个升降座21将会分别作用转动连杆23转动以带动同步横轴24转动;且转动连杆23将带动导轮231相应沿导槽232前后滑动;两侧的升降座21均能够作用同步横轴24转动,继而两侧的升降座21必须保持同步升降才能使装置稳定运行;从而能够使得定位压梁8整体将保持水平的上下运动,使得定位压梁8下压时对桌板单元a每一处施加的压力都相等,能够更有效的压住桌板单元a。Further: the positioning pressure beam 8 is also located above the supporting platform 2, and the positioning pressure beam 8 is arranged above the intersection position of the supporting bump 4a and the supporting platform 2; this is because when drilling, the table is The rear end of the table unit a is drilled; only the positioning pressure plate 7 is used to press the table unit a, and the back end of the table unit a still shakes when drilling; therefore, a positioning pressure beam 8 is also provided to further press the table unit a. The rear position of the table unit a ensures that the rear end of the table unit a remains stable during the drilling process; and the distance between the rear end of the positioning pressure beam 8 and the limit beam 4 is 1cm, so that the positioning pressure beam 8 can Press firmly on the rear punched area of table unit a. And on both sides of the rear end of the workbench 1, there are respectively second lifting electric cylinders 20 for driving the positioning pressure beam 8 to lift. The bottom of the second lifting electric cylinder 20 is provided with a lifting base 21. The second lifting electric cylinder 20 The lifting base 21 can be controlled to rise and fall; and the positioning pressure beam 8 is connected to the front end of the lifting base 21; and as shown in Figure 11, a synchronization mechanism 22 is also provided between the lifting bases 21 on the left and right sides. The synchronization mechanism 22 includes a rotating link 23 that is rotated inside each lifting seat 21, and a synchronous horizontal axis 24 connected between the rotating links 23 on both sides; there are also upward extending shafts 24 on both sides of the rear end of the workbench 1. The side support platform 25 is connected and fixed with a fixed support 26 extending forward, and the synchronous horizontal axis 24 is rotated through the two fixed supports 26; the rotating link 23 The front end is connected to the synchronous horizontal shaft 24, and the rear end of the rotating link 23 is rotationally connected to a guide wheel 231. The inner wall of the lifting seat 21 is provided with a guide groove 232 slidingly matching the guide wheel 231 along the front and rear directions; and then , when the second lifting cylinders 20 on both sides synchronously drive the lifting base 21 to move up and down, each lifting base 21 will rotate the rotating link 23 respectively to drive the synchronous horizontal axis 24 to rotate; and the rotating link 23 will The guide wheel 231 is driven to slide forward and backward along the guide groove 232 accordingly; the lifting seats 21 on both sides can synchronize the rotation of the horizontal axis 24, and then the lifting seats 21 on both sides must keep rising and falling synchronously to make the device operate stably; thus the positioning pressure beam can be positioned 8 will maintain a horizontal upward and downward movement as a whole, so that when the positioning pressure beam 8 is pressed down, the pressure exerted on each part of the table unit a is equal, and the table unit a can be pressed more effectively.
如图12所示,所述的钻孔机构9还包括用于驱动调节支座10的后驱动机构27,该后驱动机构27包括设置在调节支座10后方并连接固定在工作台1上的基板29以及两根设置在基板29上的左右间隔的导柱30;在两个导柱30上设有升降控制台28,升降控制台28能够沿导柱30升降运动;且在两个导柱30的上端设有用于控制升降控制台28升降的后升降组件31,该后升降组件31采用丝杆丝母结构,后升降组件31包括丝杆32b以及预埋在升降控制台28上端内的丝母(未图示);所述丝杆32b的下端穿设在升降控制台28上端内并与丝母螺纹配合;在升降控制台28的上方还设有数字位置显示器31a,具体的说,数字位置显示器31a位于基板29上;丝杆32b向上穿设在该数字位置显示器31a内,且丝杆32b顶部的穿出端还设有手轮(未图示);丝杆32b一般通过轴承或限位卡子被限制为沿周向转动但不轴向移动;工作时,通过转动手轮以驱使丝杆32b转动进行控制丝母升降,以调节升降控制台28升降移动,所述的数字位置显示器31a为常见的用于与丝杆32b配合的机械计数器,其能够检测丝杆32b的转动圈数,配合丝杆32b螺距,从而自动计算升降控制台28的高度位移,使得调节更加精准。例如在对18mm厚的板材进行钻孔时,可以通过控制手轮旋转,当上述机械计数器的读数为9时,就使得钻头处在板材厚度的中间位置。As shown in Figure 12, the drilling mechanism 9 also includes a rear drive mechanism 27 for driving the adjustment support 10. The rear drive mechanism 27 includes a rear drive mechanism 27 arranged behind the adjustment support 10 and connected and fixed on the workbench 1. The base plate 29 and two guide pillars 30 spaced left and right on the base plate 29; a lifting console 28 is provided on the two guide pillars 30, and the lifting console 28 can move up and down along the guide pillars 30; and on the two guide pillars 30 The upper end of 30 is provided with a rear lifting assembly 31 for controlling the lifting of the lifting console 28.

The position clamp is limited to rotate in the circumferential direction but not to move axially; during operation, the handwheel is turned to drive the screw rod 32b to rotate to control the lifting and lowering of the screw nut to adjust the lifting and lowering movement of the lifting console 28. The digital position display 31a It is a common mechanical counter used to cooperate with the screw rod 32b. It can detect the number of rotations of the screw rod 32b and cooperate with the pitch of the screw rod 32b to automatically calculate the height displacement of the lifting console 28, making the adjustment more accurate. For example, when drilling an 18mm thick plate, the handwheel can be controlled to rotate. When the reading of the above-mentioned mechanical counter is 9, the drill bit will be in the middle of the plate thickness.
且在所述的升降控制台28上还设有后推拉电缸32;该后推拉电缸32具有能够电动伸缩的伸缩主杆321,该伸缩主杆321向前穿过升降控制台28并连接在调节支座10的后端;且在调节支座10位于伸缩主杆321的两侧还分别设有向后滑动穿设在升降控制台28内的导向杆33,导向杆33能够相对升降控制台28前后滑动;进一步提高结构稳定性。继而,后升降组件31能够驱动升降控制台28并带动后推拉电缸32上下移动,从而控制调节支座10上下移动;而所述的后推拉电缸32能够驱动调节支座10前后移动。从而,在后驱动机构27的作用下,能够控制每个钻头11在避让槽孔17内上下及前后运动,从而能够预先调节初始时的钻头11的高度位置。And the lifting console 28 is also provided with a rear push-pull electric cylinder 32; the rear push-pull electric cylinder 32 has a telescopic main rod 321 that can be electrically telescopic, and the telescopic main rod 321 passes forward through the lifting console 28 and is connected. At the rear end of the adjusting support 10; and on both sides of the adjusting support 10 located at the telescopic main rod 321, there are guide rods 33 that slide backward and penetrate the lifting console 28. The guide rods 33 can be controlled in relative lifting. The platform 28 slides forward and backward; further improving the structural stability. Then, the rear lifting assembly 31 can drive the lifting console 28 and drive the rear push-pull electric cylinder 32 to move up and down, thereby controlling the adjustment support 10 to move up and down; and the rear push-pull electric cylinder 32 can drive the adjustment support 10 to move forward and backward. Therefore, under the action of the rear driving mechanism 27, each drill bit 11 can be controlled to move up and down and forward and backward in the avoidance slot hole 17, so that the initial height position of the drill bit 11 can be adjusted in advance.
且如图12所示,所述的钻头11都是预先调节好的,且各个钻头11的中心处于同一水平直线上,确保打孔后的每个孔的中心处于一条直线。在所述的调节支杆10后端的侧部设有钻头驱动电机101,在调节支杆10内部还设有横向的用于驱动各个钻头11进行同步打孔工作的齿轮同步传动机构(未图示),该齿轮同步传动机构包括同步带以及多个齿轮,通过齿轮啮合传动以提供钻头11的工作动力;继而钻头驱动电机101驱动齿轮同步机构工作能够控制各个钻头11同步进行打孔作业。And as shown in Figure 12, the drill bits 11 are all pre-adjusted, and the centers of each drill bit 11 are on the same horizontal straight line, ensuring that the center of each hole after drilling is on a straight line. A drill driving motor 101 is provided on the side of the rear end of the adjusting support rod 10, and a horizontal gear synchronous transmission mechanism (not shown in the figure) for driving each drill bit 11 to perform synchronous drilling work is also provided inside the adjusting support rod 10. ), the gear synchronous transmission mechanism includes a synchronous belt and a plurality of gears, which are driven by gear meshing to provide the working power of the drill bit 11; then the drill bit driving motor 101 drives the gear synchronous mechanism to control each drill bit 11 to perform drilling operations synchronously.

Moreover, the hole position accuracy is high, which can ensure that the center of each positioning hole 34 and the via hole 39 is kept on the same horizontal line.
步骤三:如图1-3、13-16所示,之后在桌板单元a内预埋硬质的环形的环形套管38,且在两块桌板单元a之间设置三合一连接件,其中,三合一连接件包括连接杆35以及至少设置在其中一个桌板单元a上的偏心轮结构的偏心轮紧固件36,该偏心轮紧固件36配置为用于与连接杆35卡接配合,以将两个桌板单元a拉紧拼接在一起。且步骤2中,桌板单元a的拼接侧壁a1上已经加工好了用于连接杆35穿设的过孔39;继而在该步骤中,能够进一步的将连接杆35的一端穿插并紧固于其中一个桌板单元a内。Step 3: As shown in Figures 1-3 and 13-16, then embed a hard annular sleeve 38 in the table unit a, and set a three-in-one connector between the two table units a. , wherein the three-in-one connector includes a connecting rod 35 and an eccentric fastener 36 of an eccentric structure provided on at least one of the table units a, and the eccentric fastener 36 is configured to be used with the connecting rod 35 Snap fit to tighten and splice the two table units a together. And in step 2, the through hole 39 for the connecting rod 35 to pass through has been processed on the spliced side wall a1 of the table unit a; then in this step, one end of the connecting rod 35 can be further inserted and tightened. In one of the table unit a.
具体而言:在本发明中,所述的两个桌板单元a内均设置偏心轮紧固件36与连接杆35连接配合;桌板单元a的端面在对应过孔39的位置处设有用于容置偏心轮紧固件36的嵌槽37;在该嵌槽37内预埋所述的硬质的环形套管38,所述偏心轮紧固件36嵌入在该环形套管38内且能够在环形套管38内周向旋转。具体的说:所述的环形套管38采用塑料或者金属材质制成,使其为硬质材质,不易变形,受力强度好;本发明设置环形套管38的目的是:通过在嵌槽37内预埋环形套管38,使得偏心轮紧固件36在嵌槽37内旋拧时不会与桌板单元a挤压接触,而是直接与硬质的环形套管38接触;这是由于普遍的桌板结构大致组成为:中间芯材以及芯材正反两面的硬质夹板,硬质夹板再外面是纸或贴面层;而对于一些中间芯材较软的桌板来说,比如中间的芯材是南洋楹,配备三合一连接件的话,如果偏心轮紧固件36直接与中间的芯材接触;继而当旋拧将连接杆35拉紧时,偏心轮紧固件36将会会与芯材挤压接触,而由于芯材质地较软,导致偏心轮紧固件36可能会上下歪斜的嵌入芯材中,从而导致锁紧效果变差,也影响外观。从而通过在嵌槽37内预埋硬质的环形套管38,偏心轮紧固件36直接与环形套管38接触,从而使得偏心轮紧固件36能够保持正向的旋拧,不会偏转;保证锁紧效果,且美化外观。Specifically: in the present invention, the two table top units a are equipped with eccentric fasteners 36 to connect and cooperate with the connecting rods 35; In the embedding groove 37 that accommodates the eccentric fastener 36; the hard annular sleeve 38 is pre-embedded in the embedding groove 37, and the eccentric fastener 36 is embedded in the annular sleeve 38 and Can rotate circumferentially within the annular sleeve 38 . Specifically: the annular sleeve 38 is made of plastic or metal, making it a hard material that is not easily deformed and has good stress strength; the purpose of setting the annular sleeve 38 in the present invention is to: The annular sleeve 38 is pre-embedded inside, so that when the eccentric fastener 36 is screwed in the embedding groove 37, it will not come into extrusion contact with the table unit a, but directly contact the hard annular sleeve 38; this is because The common table top structure is roughly composed of: a middle core material and hard plywood on both sides of the core material. The hard plywood is covered with paper or veneer layer on the outside. For some table tops with a soft middle core material, such as The core material in the middle is Nanyang Yingda. If equipped with a three-in-one connector, if the eccentric fastener 36 is in direct contact with the middle core material; then when the connecting rod 35 is tightened by twisting, the eccentric fastener 36 will It will come into extrusion contact with the core material, and because the core material is soft, the eccentric fastener 36 may be embedded in the core material skewed up and down, resulting in poor locking effect and affecting the appearance. Therefore, by pre-embedding the hard annular sleeve 38 in the embedding groove 37, the eccentric fastener 36 directly contacts the annular sleeve 38, so that the eccentric fastener 36 can maintain forward screwing and will not deflect. ; Guarantee the locking effect and beautify the appearance.
其中,偏心轮紧固件36的横截面为圆形,所述嵌槽37相应设置为圆形槽;环形套管38配置为卡紧嵌入在嵌槽37内,且两者为过盈配合;使得环形套管38嵌入在嵌槽37内后,不会脱离嵌槽37。如图16所示,在所述的环形套管38的外壁上均匀设有呈波浪状分布的外凸齿38a;该外凸齿38a使得环形套管38嵌入在嵌槽37内的过程中,环形套管38与嵌槽37之间的接触面积减小,使得环形套管38更容易嵌入配合在嵌槽37内;且环形套管38嵌入在嵌槽37内后,所述外凸齿38a还能够增加两者的摩擦力,使两者连接紧密,环形套管38不会在嵌槽37内偏转。再者,所述的环形套管38的高度与嵌槽37的纵向深度相一致。使得环形套管38嵌入在嵌槽37内后,环形套管38的上端面与桌板单元a的上端面齐平,使结构美观。继而使得偏心轮紧固件36将始终与环形套管38接触配合,不会与桌板单元a的内芯挤压接触;保证连接结构稳固。Among them, the cross section of the eccentric fastener 36 is circular, and the embedding groove 37 is correspondingly set as a circular groove; the annular sleeve 38 is configured to be clamped and embedded in the embedding groove 37, and the two are interference fit; After the annular sleeve 38 is embedded in the embedding groove 37, it will not break away from the embedding groove 37. As shown in Figure 16, the outer wall of the annular sleeve 38 is evenly provided with external protruding teeth 38a distributed in a wavy shape; the external protruding teeth 38a enable the annular sleeve 38 to be embedded in the embedding groove 37, The contact area between the annular sleeve 38 and the embedding groove 37 is reduced, making it easier for the annular sleeve 38 to fit into the embedding groove 37; and after the annular sleeve 38 is embedded in the embedding groove 37, the outer convex teeth 38a It can also increase the friction between the two, so that the two are tightly connected, and the annular sleeve 38 will not deflect in the embedded groove 37 . Furthermore, the height of the annular sleeve 38 is consistent with the longitudinal depth of the caulking groove 37 . After the annular sleeve 38 is embedded in the embedding groove 37, the upper end surface of the annular sleeve 38 is flush with the upper end surface of the table unit a, making the structure beautiful. Then, the eccentric fastener 36 will always be in contact with the annular sleeve 38 and will not be in extrusion contact with the inner core of the table unit a; thus ensuring a stable connection structure.
如图13-15所示,所述的过孔39一直延伸至与嵌槽37贯通;所述环形套管38上对应设有使连接杆35穿过的槽口40。此外,在所述偏心轮紧固件36上端面的中心位置处开设有内六角沉槽36b;传统的偏心轮紧固件36采用十字沉槽,而由于本发明增设了环形套管38,增加了连接处结构强度;偏心轮紧固件36能够承受更大的旋拧力,故而在偏心轮紧固件上设置内六角沉槽36b,能够采用L型的内六角扳手进行旋拧偏心轮紧固件36,使操作更为省力轻松;至于三合一连接件具体的连接方式为常见的现有技术,并非本发明的设计要点,故而在本实施例中不做过多赘述。再者,在所述环形套管38的内壁上还均匀设有呈波浪状排布的内凸齿38b;相应的,在所述偏心轮紧固件36的外壁上设有滚花纹36a;能够增加环形套管38与偏心轮紧固件36之间的摩擦力,使偏心轮紧固件36在环形套管38内旋拧后,不会回退;起到止退作用。继而在该步骤中,将连接杆35先与其中一块桌板单元a上的偏心轮紧固件36卡接配合。As shown in Figures 13-15, the through hole 39 extends until it penetrates the embedding groove 37; the annular sleeve 38 is correspondingly provided with a notch 40 for the connecting rod 35 to pass through. In addition, an internal hexagonal sink groove 36b is provided at the center of the upper end surface of the eccentric fastener 36; the traditional eccentric fastener 36 adopts a cross sink groove, but due to the addition of an annular sleeve 38 in the present invention, additional The structural strength of the connection is increased; the eccentric fastener 36 can withstand greater twisting force, so an internal hexagonal sink groove 36b is provided on the eccentric fastener, and an L-shaped internal hexagonal wrench can be used to tighten the eccentric The firmware 36 makes the operation more labor-saving and easier; as for the specific connection method of the three-in-one connector, it is common in the prior art and is not a design point of the present invention, so it will not be described in detail in this embodiment. Furthermore, the inner wall of the annular sleeve 38 is evenly provided with internal convex teeth 38b arranged in a wavy manner; correspondingly, the outer wall of the eccentric fastener 36 is provided with knurled patterns 36a; The friction force between the annular sleeve 38 and the eccentric fastener 36 is increased so that the eccentric fastener 36 will not retreat after being screwed in the annular sleeve 38; thus, it plays a role of stopping the retreat. Then in this step, the connecting rod 35 is first engaged with the eccentric fastener 36 on one of the table unit a.
步骤四:然后在其中一个桌板单元a的定位孔34内依次穿设定位销41;该定位销41配置为与定位孔24插接配合;且定位销41采用金属钢管制成;保证结构强度。Step 4: Then insert positioning pins 41 in sequence in the positioning hole 34 of one of the table unit a; the positioning pin 41 is configured to plug-fit with the positioning hole 24; and the positioning pin 41 is made of metal steel pipe; ensure the structure strength.
步骤五:之后将两个桌板单元a拼接在一起,使定位销41两端分别穿插在两块桌板单元a的定位孔34内;连接杆35的两端也相应分别穿插在两块桌板单元a的过孔39内;此时,两个桌板单元a的拼接侧壁a1初步拼接在一起。Step 5: Then splice the two table units a together so that both ends of the positioning pin 41 are inserted into the positioning holes 34 of the two table units a; the two ends of the connecting rod 35 are also inserted into the two table units. In the through hole 39 of the board unit a; at this time, the spliced side walls a1 of the two table board units a are initially spliced together.
步骤六:最后旋拧作用于偏心轮紧固件36,偏心轮紧固件36将拉紧作用于连接杆35以使两块桌板单元a锁紧。最终通过旋钮偏心轮紧固件36以进一步的使得两个桌板单元a之间拼接处更加紧密,实现两块桌板单元a之间的稳固拼接。进一步说:所述定位销41的直径大于连接杆35的直径(钻头11的直径能够预先设置好);使得定位销41是粗于连接杆35的,继而连接后定位销41主要起到承载受力的作用,当其中一块桌板单元a受挤压力时,由定位销41进行分散受力;而连接杆35主要起到将两块桌板单元a拉紧的作用;两者各司其职,避免连接杆35受力导致松动,使两块桌板单元a始终能够锁紧。且如图2所示,连接杆35包括杆体以及分别位于杆体两端用于连接的杆头;所述的定位销41的长度与杆体的长度是趋于相等的;这样设计的目的在于:当两个桌板单元a拼接后,其中一个桌板单元a受到挤压作用力时,杆体以及定位销41两端的受力下压点处于同一条轴线上;使得结构受力更加均匀分散。再者,由于在步骤二中,采用排孔装置B使得桌板单元a上孔位的加工精度高,使得定位销41和连接杆35均处于同一高度;使得拼接时,两个桌板单元a之间拼接平整度更好,且结构受力更佳;不会使得拼接处凹凸不平整。Step 6: Finally, tighten the eccentric fastener 36, and the eccentric fastener 36 will tighten the connecting rod 35 to lock the two table units a. Finally, the knob eccentric fastener 36 is used to further make the splicing between the two table units a closer, thereby achieving a stable splicing between the two table units a. Furthermore: the diameter of the positioning pin 41 is larger than the diameter of the connecting rod 35 (the diameter of the drill bit 11 can be set in advance); so that the positioning pin 41 is thicker than the connecting rod 35, and then the positioning pin 41 mainly serves as a load bearing after connection. Due to the force, when one table unit a is subjected to extrusion force, the positioning pin 41 distributes the force; and the connecting rod 35 mainly plays the role of tightening the two table units a; each performs its own function. position to prevent the connecting rod 35 from loosening due to force, so that the two table unit a can always be locked. As shown in Figure 2, the connecting rod 35 includes a rod body and rod heads located at both ends of the rod body for connection; the length of the positioning pin 41 and the length of the rod body tend to be equal; the purpose of this design is: After the two table units a are spliced, when one of the table units a is subjected to an extrusion force, the pressure points at both ends of the rod body and the positioning pin 41 are on the same axis, making the structural stress more evenly distributed. Furthermore, in step two, the hole row device B is used to achieve high machining accuracy of the holes on the table unit a, so that the positioning pin 41 and the connecting rod 35 are at the same height; so that when splicing, the two table units a The splicing between them is smoother, and the structure is better stressed; it will not make the splicing joint uneven.
综上,本发明的桌板加工及拼接工艺,桌板单元a采用排孔装置B进行加工定位孔34和过孔39,加工效率高,且孔位精度好。其次,在嵌槽37内预埋硬质的环形套管38,避免偏心轮紧固件36挤压桌板单元a的内芯导致连接不稳固;使得三合一连接件的连接效果更佳,结构更加稳定;而采用定位销41承载受力,采用连接杆35拉紧桌板单元a;最终使得桌板单元a加工方便,且两个桌板单元a之间拼接结构更高,拼接后的平整度更佳。In summary, in the table processing and splicing process of the present invention, the table unit a uses the hole row device B to process the positioning holes 34 and the through holes 39, which has high processing efficiency and good hole position accuracy. Secondly, a hard annular sleeve 38 is pre-embedded in the embedding groove 37 to prevent the eccentric fastener 36 from squeezing the inner core of the table unit a and causing an unstable connection; making the connection effect of the three-in-one connector better, The structure is more stable; the positioning pin 41 is used to bear the force, and the connecting rod 35 is used to tighten the table unit a; ultimately, the table unit a is convenient to process, and the splicing structure between the two table units a is higher, and the spliced Better flatness.
